Mike:
Last week:
* Mailinglist posts about two guards & QUIC
* Meetings about other funding proposals, personel
* (re)read a handful of research papers, filed tickets
* Some ticket review
This week:
* Xfer two guards thread -> proposal. Does anyone have any other
points/concerns/arguments?
* TL;DR is that one guard is not any better than two, and
arguably worse, because our path restrictions allow an adversary to
force the use of a second guard at any time for specific activity. I
am assuming we want to keep our path restrictions. Is this correct?
* Relatedly, in order to prevent the adversary from being able
to force the use of a *third* guard, we also need to ensure that the
two guards we pick are not covered by the same path restrictions (ie
must be chosen from different /16 and family).
* Trim down prop247 to cover what we are doing with the vanguard
script (which will also match our planned final implementation).
* Review other tickets. (Are we deliberately assigning a new
person to review a ticket each time it goes back to needs_revision?
This seems expensive, but does mean more eyeballs)
[dgoulet]: No, if it goes back in needs_revision, the original
Reviewer stays as is and in charge of reviewing again when it goes
back in needs_review.

[dgoulet] Awesome!
[asn]: epic
juga
Last week:
* collecting questions for the virtual "bandwidth authority team"
* bwscanner:
* started merging PRs without review
* solved some bugs and PRs
* cleaned up not used code

* sbws: still not sure whether to dedicate time on it or continue
with bwscanner

bwscanner to do not generate traffic
* funding:
* received negative answer from previous funding attempt (aka F1)
* submitted application for new funding attempt (aka F2)
* writing application for new funding attempt (aka F3)
Next week:

(https://github.com/TheTorProject/bwscanner) u#111, #94, others
* document better what is doing
* try run it with shadow?
* funding: submit application for F3 (deadline sat)
* time for working on #25515?
* i would like to join this meetings to continue sharing updates and
discuss bwscanner questions when i have them. - is this cool w/ the
team?, and where/when/who i could send questions that would talk
longer to discuss?
pastly:
sbws (simple bw scanner) is my attempt as a bw scanner
been running some scans primarily for timing information
got set up on ln5's donated box
next steps:
come up with and implement an intelligent scan order for relays
sphynx documentation
catalyst:

asn:
Last three weeks:
- Attended Rome meeting!
- Gave Tor talk in ENS Paris. Gave talk in Tor meetup hackfest in Athens.
- Worked on network team roadmapping and worked on spreadsheets for
roadmap and metadoc.
- Worked on SponsorBucket roadmapping and briefed team about
upcoming Snowflake position.
Need help from Roger/Isa on figuring out next steps based on my
last email to the thread.
- Handed over the first round of weekly reviews with David.
- Reviewed #17799, #24767, #24989, #6236.
- Setup github account, github repo and travis and started
transitioning there: https://github.com/asn-d6/tor
- Discussed switching to 2 entry guards with Mike on [tor-dev]. I can be
persuaded that it's a good idea but we need a proposal.
- Worked on #14389 (UX of client auth for onions) with Arthur and
David. Need more little-t-tor work and analysis.
- Opened ticket about rev counter issue found by Roger and made an
implementation plan: #25552
This week:
- More reviews.
- Start working on my vanguard simulation again. My goal is to have something
initial on github by the end of the week, so that Mike can start using it
in a week or two.
- Need to do more work on #20212 and #25609 so that we can move forward
there. Some mikeperry wisdom might be needed there.
